. and l do declare the following to be afull,

, clear, and exact description of the invention,

i such as will venable others skilled in the art las titi

to which it appertains Ato make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to a device for purifying oils which have been used for lubrieating purposes, and is4 designed. to remove dirt, sediment and metallic particles in orde-r to render such oils lit for re-use.

' To this endl my invention consists of the devices and construction hereinafter described, and Shown and illustrated in the accompanying drawings, in which- Figure 1, is a side-elevation of an apparatus embodying the principles of vmy invention, this figure being' partly in vertical section, and Fig. 2, atop plan-view in section, taken on line :z2-a, Fig. Tl.

Like numerals indicate like parts throughout the drawings.

ln the drawings, -l is an elevated container for the oil to be treated. From the bottom of this container leads a pipe 2V into the lower partof the chamber of a vessel 3. The lower part of this chamber is filled with water up to line 4. From the top portion of the chamber of vessel 3 leads a pipe 5 into a vessel 6 designed for the reception of the clean oil. ln the chamber of, the vessel 3 is a series of permanently magnetized plates 7 disposed one above another and inclined alternately at opposite inclinations. The lower edge of each of these plates .rests against thefend-/walls of the vessel 3, so that oil enteringf the chamber ofthe vessel 3 below the lower plate 7 will, by reason of' its levity, move upwardly in a zigzag' or sinuous course alone' the under side of each cf the plates 7' until it reaches and rests in the Vessel 6 4to a predetermined height.

or heating the contents' of the vessel and which is found to greatly expedite the puriication process.

The operation of my device will now be obvious.

rlhe dirty oil from tank l passes through a strainer, not shown, down through .pipe 2 into the bottom in the-chamber of vessel 3 and below the lower plate 7. By means of cock 10 this flow of oil is restricted so that the oil is fed into the'vessel 3 in large drops which A'roll upwardly along the under side of the successive plates 7. The steel particles carried by the oil are caught and retained by the magnetic plates; otherparticles are, by the slight agitation of the drops of oil -in the water, washed from the 'oil and these settle upon the bottomsof the vessel 3 or upon the topofthe plates 7,'the result being, that when ,the oil' passes out from beneath the top plate 7, it has given up -lt will be seen that by'removini,r the cover 3", the plates 7 may be readily lifted outfthe contents of the vessel having" been first 'withdrawn through a cock not showin-and now the plates and the entire vessel may 'be readily cleansed by a steam-jet or otherwise as maybe desired.

While l have shown but one of the vessels 3 'and itscontents it is evident that there may be a series of such vessels connected to gether and interposed between the tanks 1 and 6.. lt is also evident that there will suggest themselves various modications of my deviceby which dirty oils may be caused to percolate upwardly through a body of water and in the presence of magnets, to remove impurities, which is `the essence of my invention, and l do not, therefore, limit mv invention to the'y structural details here indicated. i

Havingr described my invention., what l claim and desire to 'secure by Letters Patent.. is v l.. ln an apparatus of the described character, a vessel. in the vessel a body of liouid of greater gravity than oil, means for feedine' oil into the lower part of such bodv of liquid, and a series of oppositely inclined ln the bottom of the chamber of the tank 3 y is a steam or hot water coil 9 for warming f permanently magnetized plates disposed one above another, the lower edges of alternate plates resting against opposite walls of the vessel, whereby there is formed an yupward sinuous path through said body of liquid.

'n 2. I n an apparatus of the'described 'character, an elevated tank for dirty oil, a tank for clean oil, an intermediate vessel having its chamberconnected at bottom with said dirty oil tank and at top with said clean oil tank, and a series of oppositely inclined permanently magnetized plates in said intermediate vessel disposed one abovean# -nently magnetized plates in said intermediate vessel disposed one above another, a body of liquid in said intermediate vessel of greater gravity than oil, the arrangement of the magnets being such that a sinuous path is formed for oil moving upwardly through said body of liquid.

4. An apparatus of the described char- .acter comprisingl a vessel, the chamberof which has an inlet near its bottom and an outlet nearits top, in the chamber of said vessel a series of permanently magnetized plates disposed one above .another andinclined upwardly and alternately at opposite inclinations, the lower edges of alternate plates resting against opposite walls of the vessel, whereby there is formed an up ward sinuous path from said inlet toward said outlet, means for the detachable support of said plates, a body of liquid in said vessel which submerges said plates, and means for heating said body of liquid.

In testimony whereof I aix my signature in presence of two witnesses.
